METHOD OF APPLICATION OF WEAR-RESISTANT COATINGS BASED ON TITANIUM AND NICKEL CARBIDE ON STAMPS

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to the formation, on steel surfaces, of coatings based on titanium and nickel carbide, which can be used in stamping and other industries. Method includes an electric explosion of a composite electrically exploding conductor consisting of a two-layer flat nickel shell with a mass of 60–530 mg and a core in the form of titanium carbide powder with a mass equal to 0.5–2.0 of the shell mass, formation from the explosion products of a pulsed multiphase plasma jet, its fusion with the surface of the die steel at an absorbed power density of 4.6–4.8 GW/m², deposition of explosion products onto the surface with formation of a composite coating of the TiC-Ni system on it and subsequent pulse-periodic electron-beam treatment of the coating surface at an absorbed energy density of 40–60 J/cm², the pulse duration is 150–200 microseconds and the number of pulses is 10–30.;EFFECT: invention is aimed at creating a wear-resistant coating on the surface of the die steel with high adhesion to the substrate at the level of cohesion.;1 cl, 2 ex, 2 dwg
